6 Claims.

This invention relates to transom operators, and more specifically totransom operators for use with steel easement windows.

As is well known, the frames of such windows are relatively narrow,affording little space for the mounting of operators of the generalclass above noted and the available space is further reduced through thenecessity in many locations of applying screens to the sash and transomopenings. Accordingly, important objects of this invention are theprovision of an operator which will require a very small space for itsapplication, which may be readily installed upon the frame, and in whichthe more unsightly portions of the o operating mechanism are effectuallyconcealed from view and protected from the weather when the transom isclosed. g

A further object of the invention is the provision of an operator ofthis character which will permit the transom to be opened with theapplication of a relatively small force and will, at the same time, holdthe transom securely in any adjusted position thereof.

These and other objects I attain by the construction shown in theaccompanying drawings wherein, for the purpose of illustration, I haveshown a preferred embodiment of my invention and wherein:

Fig. l is a front elevation of a transomed sash frame including atransom operator constructed in accordance with my invention;

Fig. 2 is a side elevation thereof;

Fig. 3 is a section on line 3--3 of Fig. l;

Fig. 4 is a fragmentary perspective view, parts being broken away toshow the construction and mounting of the mechanism; and

Fig. 5 is an enlarged section on line 5--5 of Fig. l.

Referring now more particularly to the draw- 4() ings, the numeral I0generally designates a sash frame comprising-aperimetric frame member IIwhich is substantially L-shaped in cross section, and horizontal andvertical dividing rails I2 and I3 which are substantially T-shaped incross section, these dividing rails subdividing theframe into openingsfor the reception of a transom T and the usual sash. The transom Tcomprises a frame member I4 which is likewise substantially L-shaped incross section, this frame member combining with rail I2 and the sashframe in the closed position of the transom to form a substantiallyrectangular closed channel I5. The transom is hinged .at its upper endas indicated at I6 to swing to open and closed positions and is soproportioned that proper clearances are provided between the flanges ofits frame and the flanges of the sash frame until the transom arrives atits closed position, these clearances, however, being relatively slightas in the usual swinging sash construction.

-In .accordance with my invention. I arrange wlthn the lower run of thechannel I5, that is to say, that run formed by the rail I2 and the loweredge of the transom. a pair of shafts I1, these shafts being arranged inbearings I8 secured to the stem portion I9 of the T member forming therail I2.

Secured to the outer ends of the shafts I1 are thin flat arms 20, thewidth of these arms being such that they may readily pass through theclearance space provided between the flanges of tle sash frame andtransom as the transom is opened or closed. To the sides of the transomframe and against the riser I of the L-shapecl member forming thisframe, I secure an elon- L gated slide guide 22 within which a slide 23is mounted, this slide being pivotally connected to the frame end of theassociated arm at 26.

To the adjacent ends of shafts I1 I secure relatively short arms 25,these arms projecting through slots 26 formed'in the head of the Tmember forming the rail I2. Upon the rail I3 at a convenient level, Imount a casing 21 within which a gear nut 28 is disposed, this nutcoacting with a worm 29 formed upon the lower end of a shaft 30. Thisnut may be rotated I through a crank-operated pinion 3|, thus causingshaft 30 to rise or fall as desired. The upper end of this shaft has afurcate head 32 provided with an abutment 33 to slide against the faceof the rail I3 and in the furcation of this head a link 34 is pivotallymounted. Link 3l is, in turn, pivotally connected to the adjacent endsof arms at 35 and it will, accordingly, be obvious that as shaft risesand falls the shafts I1 will be rotated and by their rotation will causethe transom T to move about its hinges.

Shaft 30 is necessarily relatively long and, accordingly flexible, andto rmly hold the upper end thereof in properly guided relation and, atthe same time, to conceal the connections which are made between theshaft and arms 25, a casing 3B is provided. This casing has a notch 31for passage of shaft 30 which is of such depth that when the casing isin applied position it holds the shaft with the abutment 33 in properengagement with the wall of the rail I3. While a single shaft might beemployed in lieu of the shafts I 1, the construction illustrated ispreferred for the reason that steel easement sash often becomes sprungand will not fit tightly at opposite sides thereof except by independentadjustment which is, of course, afforded by the double shaftarrangement.

It will be noted that the operator parts which are disposed at the faceof the window are of relatively restricted size and may be readily sodisposed that they vdo not interfere at all with the application ofscreens to the window. Shafts l1 and the arms 20 are fully protectedfrom the weather wherf the transom is in a closed position.

While I have described the invention in conjunction with a hingedstructure, `it will, of course, be obvious that the` same constructionmay be readily employed with the projectedvtype of sash mounting.

Since the construction is obviously capable of considerable modificationwithout departing from the spirit of the invention, I do not wish to beunderstood as limiting myself thereto except as hereinafter claimed.

I claim:

1. A frame including a horizontal cross member defining a transomopening, a transom hinged to the frame at the upper edge of the opening,said transom and frame combining in the closed position of the transomto define a closed channel extending about the free edges of thetransom, a shaft in the lower run of the channel, means to rotate theshaft from the exterior of the channel and` operative connectionsbetween the shaft and transom constructed and arranged to move thetransom about its hinges as the shaft is rotated. y

'2. A frame including a horizontal cross member dening a transomopening, a transom hinged to the frame at the upper edge of the opening,said transom and frame combining in the closed position of the transomto define a closed chan# nel extending about the free edges of thetransom, a pair of shafts in the lower run of the channel, means tosimultaneously rotate the shafts from the exterior of the channel andoperative connections between the outer ends of .the shafts and sides ofthe transom constructed and arranged to move the transom about itshinges as the shaft is rotated.

3. A frame yincluding a transom opening, a transomhinged to the frameat'one edge of the opening, said transom and frame each' comprisingrectangular frame elements L-shaped in cross section, said frameelements combining in the closed position of the transom to produce ahollow channel, the flanges oi' said L-shaped members passing oneanother in slightly spaced relation as the transom moves from open toclosed positions, a shaft secured to the frame within the channelthereof at the side of the frame opposite that to which the transom ishinged, an arm secured to the shaft and movable through the spacebetween the flanges of the frame and transom as the transom is movedfrom open to closed positions and disposed within a channel at the sideof the transom and frame' when the transom is in closed position, meansto rotate said shaft and a slide carried by the transom within thechannel of a side member thereof and pivotally connected to the free endof Asaid arm.

4. A device as claimed in claim 1 wherein the shaft has an armprojecting through a slot formed in the wall of the channel and alongitudinally movable shaft has linked connection with the free end ofsaid arm.

5. A device as claimed in claim 1 including a longitudinally movableshaft having a screw thread at one end, a nut engaging said thread andguiding said end of the shaft, means to rotatetsaid nut and a link andarm connection between the opposite end of the longitudinallyk movableshaft and the first-named shaft.

6. A device as claimed in claim 1 including a longitudinally movableshaft having a screw thread at one end, a nut engaging said thread v andguiding said end of the shaft, means to rotate said nut, a link and armconnection between the opposite end oi.' the longitudinally movableshaft and the first-named shaft, the arm being attached to the shaft andprojecting -through a slot in the channel wall, and a housing cover forsaid link and arm connection concealing the same from view and guidingthe adjacent end of the longitudinally movable shaft.
